CHARLES l. BTZ, OF ST. LOUIS, MISSOURI.

Application filed January 7, -1929.

My invention relates to improvements in loose leaf` binders, and has forits primary object a loose leaf binder which is readily adjustable for avarying number of pages.

A further object is to construct a loose leaf binder in which the pagesare securely held and in which no screws, rings or springs are employedfor holding the pages.

A still further object is to vconstruct a loos-e leaf binder in whichthe pages can be readily removed and new pages inserted without thenecessity of employing tools for that ur ose. f l A still further objectis to construct a loose leaf binder having a flexible back, which backis formed of one piece and is adjustable for various thicknesses ofbook.

In the drawings:

Fig. 1 is a top plan view of my device withv parts broken away.

Fig. 2 is a fragmental view of the book inopen position showing themanner of releasing the page holder.

F ig. 3 is a section of Fig. 1.

Fig. 4l is an enlarged fragmental edge view of the binder.

Fig. 5 is an enlarged section taken on the line 5-5 of Fig. 1.

Fig. 6 is a perspective view of one of the back clamps employed. l

Fig. 7 is an enlarged cross sectional view of the page holder.

Fig. 8 is a perspective view of a modified construction of covershowingthe holding taken on the line 3-3 members partially inserted inthe pocket and the page holder members in perspective on said cover andpartially assembled.

Fig. 9 is a perspective view of the cover with tbe page holding membersassembled yand in position thereon and one of the securing members readyto secure the page holding members together; and

Fig. 1() is a perspective view of one of the holding members.

In th-e construction of my device I employ a cover having a front member8 and a back member 9. These members are preferably made stiff and areconnected together by a flexible strip 10 which forms a hinge betweenthe two covers so that the same can be opened without breaking over thecover. Passing partially around the back or hinge 10 are back clamps 11,which a-re in the form of doubleended books and which when placed inposi- LOOSE-LEAF BINDER.

tion on the back form a pocket 12 for the reception of tongues 13 of theholding members 14. These holding members are substantially U-shaped andare provided on one end with wings 15. Located within the cover are pageholders 16 and 17. These page holders are substantially L-shaped incrosssection and have their ends 18 and 19 bent back upon themselves soas to form passageways 20 into which the wings 15 pass. Y

Carried by the turned-in portion 18 is a pin 21, which lits within asleeve 22 carried by the turned-in portion 19.

It will. be noted that the members 16 and 17 overlap so that the pin 21telescopes into the sleeve 22. The pages 23 are provided with the usualperforations which are of such a size as to readily pass over the sleeve22.

It will be noted from Figs. 5 and 7 that the passageways 2O areunobstructed. In other words, neither the pin 21 nor sleeve 22 eX- tendsinto this passageway.

The assembling of the book is as follows:

The back clamps 11 are first placed in position on the back so as toform a pocket of suflicient width to receive the tongues 13'of thcholding members. The holding members are pulled out as indicated at theright side of Fig. 2. Then the page holders 16 and 17 are separated andthe pages placed over the sleeve 22 after which the pin 21 is insertedin the sleeve 22 and the members pushed together until they bear againstthe inserted pages. The holder is then placed within the ycovers and theholding` members 14 pushed inwardly so that the'wings enter thepassageways 20 thus preventing the members 16 and 17 from becomingseparated.

From the foregoing it will be seen that no tools at all are necessary inorder to secure the pages within the covers.

As more pages are added to the binder, that portion of the holdingmembers 141 containing the'wings 15 is made wider and in order tocompensate for this increase in width, the tongues 13 are made narrower.Then when a wider holding member is used, the back clamps 11 are movedbackward on the back or hinge member 10 thus decreasing the size of thepocket 12 thus permitting the back or hinge to adjust itself in widthcorresponding as the book increases in thickness.k In other words asthat portion of the holding member having the wings is increased inwidth, the tongue 13 is decreased so as to permit the back are located.

,lfn lligs. 8 and E) I have shown my cover in which a pocket ispermanently termed by means of a row ot `titching :24 and in thispocketthe ends l-l Y holding members lll are inserted. lWhen the deviceis constructed in this n'ianner it will be un dcrstood that the pocketis not acljustable and consequently the tongues or ends 113 oi themembers ll must all be of a uniform width regardless ot 'the width otthe end having the wings l5.

llilhilc I have shown my device with only two sleeves and pins, I do notdesire to limit myself to this particular construction as I may use morepins depending entirely, of course, on the size ot' the page.

Having fully described my invention, what I 'claim is l. A loose leatljiindcr comprising a pair ot covers, a `ilegible back tor hingedlyconnecting said covers and havin a pociicd formed in said back, a.plurality et pages removably located between said covers, and meansincluding a member extending into the ends ot' said pocket for holdingsaid pages within said covers.

2. A loose leart binder comprising a pair of covers, a flexible back forhingedly connecting said covers and having, an adjustable pocketYl'ormed in said back, a plu ality of pages reinova bly located betweensaid covers, an d means includ ing a member extending into said pocketfor holding said pages within said covers. 4
